Racing Cylinder from SIP PERFORMANCE with parts certificate for 125 cc Vespa Models.

Engine update with TÜV approval. The easiest way to make your scooter legally faster. Since January 2013, there is no longer an 80 km/h limit for class A1 light motorcycles. This opens up completely new perspectives in the field of legal tuning. As original PX80 Cylinders have not been produced for a long time, anyone looking for a replacement Cylinder for their PX80 had to either fall back on a used part or install a Racing Cylinder with 135 cc or 139 cc. However, the latter was not legally possible for riders with a "small license" up to 125 cc.

• Lower costs for registration
• Secure basis for registration without problems with the test center
• Legal, safe and fast on public roads

The SIP 125 cc Racing Cylinder, which we have legalized with a parts certificate, provides a remedy. This means that it can be easily registered with the TÜV without expensive performance, brake or noise measurements. To keep thermal expansion as low as possible, the Cylinder is equipped with a Meteor Piston with 1.2 mm Piston Rings. This promises minimum wear and maximum durability. The specially revised Cylinder Head also ensures the correct compression.

If the Engine is already old or has many kilometers behind it, an engine overhaul is recommended before the conversion. Crankshaft bearings, Oil Seals and Cruciform in particular are typical wear parts on Vespa two-stroke engines.

The kit is also a good basis for further tuning. Caution: However, this invalidates the parts certificate. Opening up the Engine, for example, offers the possibility of changing to a better Crankshaft. If open-heart surgery is being carried out anyway, the tuning should be sensibly rounded off with tuned transmission components.
